Home office bang for buck amp - Musical Fidelity Merlin or Yamaha WXA-50

Hi all.

I'm currently setting up a home office room and am in need of a small amplifier to power an pair of Dynaudio Audience 42s to act as some monitor/computer speakers.

I've largely narrowed the choice down to either a used Musical Fidelity Merlin amplifier or a Yamaha WXA-50.

Superficially both look very similar in terms of power output / input output etc.

I plan to run audio from my computer to the amp over optical/toslink (both amps seem happy to accept 24bit/192kHz).

Broadly speaking people seem to speak highly of the WXA-50.  Apparently it uses uses an ICEpower 125ASX2 and just generally everyone seems happy with it.

The only downside I see is that it lacks a headphone output.  Not strictly a deal-breaker for me as I don't listen to cabled headphones but the option would be nice.

The Merlin is curious as I cannot find much in the way of good information on it. There's a couple of articles around but they read a bit like advertorials.

From what I can tell it's essentially a V90-AMP with some extra features - and it is typically sold with some strange-looking elliptical speakers.

The V90-AMP itself seems to have some mixed opinions - but I'm unsure if issues raised are present in the Merlin and/or whether people are comparing the amp to other full-price MF gear over its price-point peers.

Does anyone have any insight here?

Am I crazy to try running 4ohm 86dB Dynaudio speakers from a diminutive Class-D amp?

Between the two, I'm probably leaning a little towards the Yamaha WXA-50 but happy to be warned off.
